This item has two functions, a quick release body and an Air Adjusting Valve.

The Air Valve offers control of airflow at the airbrush. This allows the airbrush to spray anything from a coarse stippling effect, to a full atomisation with a simple quick turn. When doing fine line or detail work, adjust the Air Valve to create optimum airflow for maximum control of paint output. Fully open the Air Valve and this will enable you to spray wide background areas and to quickly clean the airbrush during colour changes with ease.

The Quick Release body is a connector that is screwed into the end of your air hose (this fits all 1/8 standard hose fittings) and by simply sliding the spring loaded sleeve back, the airbrush can be disconnected easily. By adding a Quick Disconnect Plug adapter to your airbrush, this enables you to switch quickly to different airbrushes by plugging them in.
